Why would a DevOps team choose GitLab over GitHub for a single-platform workflow?

The main pull toward GitLab for DevOps-heavy teams is consolidation: source control, CI/CD, container registry, security scanning, and issue tracking all live in one product with one permissions model, instead of GitHub plus GitHub Actions plus a separate registry plus a third-party security scanner plus Jira.

That matters operationally in a few concrete ways. CI/CD variables, protected branches, and approval rules can be set once at the group level and inherited by every project underneath it, rather than configured app-by-app. Security scanning results (SAST, dependency scanning) show up directly inside the merge request diff on Premium/Ultimate, so reviewers don't have to context-switch to a separate dashboard. And because Auto DevOps and the Container Registry are native, a team can go from a fresh repository to a deployed, scanned container image without installing any GitHub Marketplace actions from third parties.

This isn't a universal win: GitHub still tends to have the larger open-source contributor base and marketplace of reusable Actions, so the right choice depends on whether a team values a unified DevOps toolchain more than ecosystem size and community reach.
